     // Wheel events come in two flavors:
     // The ScrollByPixelWheelEvent is a fine-grained event that specifies the precise number of pixels to scroll.  It is sent directly by MacBook touchpads on OS X,
     // and synthesized in other cases where platforms generate line-by-line scrolling events.
     // The ScrollByPageWheelEvent indicates that the wheel event should scroll an entire page.  In this case WebCore's built in paging behavior is used to page
     // up and down (you get the same behavior as if the user was clicking in a scrollbar track to page up or page down).
